The invention relates to an acceleration test method of an elastomer material in a simulated environment of a proton exchange member fuel cell, which comprises the following steps of: selecting an elastomer material sample, cleaning and drying the elastomer material sample; preparing a hydrofluoric acid and sulfuric acid test solution; putting the elastomer material sample into the test solution to be aged; periodically taking out the elastomer sample, cleaning and drying; and analyzing and testing the dried sample, recording the weight of the sample in each analytic test in various test environments, making a curve of change of weightlessness of the sample along the aging time, and analyzing the acceleration test rule. According to the acceleration test method, the damage process of the elastomer material can be accelerated, the test period can be shortened, and the ageing process can be accelerated for several times or dozens of times; and the ageing process of the elastomer material can be researched in a lab within a shorter time, so that a best acceleration service life test method can be provided for predicting the service life of the elastomer material under the actual working condition.
